Spotted these 2 images online and I was amazed. Supposedly this is Dixie Carter, Lily Tomlin and Madeline Kahn doing a stage act together in 1963 in New York City. I didn't even know they knew each other, let alone did an act!
In fact the web and Wikipedia pages for all 3 women mention no such act although all do place them as doing stage comedy on the east Coast at that time.
I thought at first this might be some 1980s TV bit where they pretended to be their younger selves but Lily does, in fact, look quite different than she did by the 1980s.
